(Gran wander the not oi 3, sees, as amended April M23; 376 {B ll '35?) This invention described herein may be mmu iactured and used by or tor the Goveent for goveental purposes, without the pent to us of any royalty thereon.

g This invention relates in general to receptacle closures and more particularly has reference to a removable seal for a gas mask carrier.

It is customary after the assembly of gas mask units not intended for immediate use to pack the same in an airtight container charged with an inert gas to prevent deterioration of the rubber and fabric. Previous to this time diiflculty has been experienced in obtaining an effective seal for containers of this character which may be readily u removed when it is-desired to employ the mask packed therein. I I

An object of this invention is to provide a gas, mask carrier having a hermetic seal which may be quickly opened for removal oithe mask. so 'Another object of this invention is to-provi a gas mask carrier having a hermetic seal protected against mechanical injury. p

Still another object of this invention'is to provide a gas mask carrier having a hermetic seal 25 protected against rupture by pressure resulting from expansion or contraction of the fluid con- 'tainedin the carrier by reason oi temperature changes.

A further object or this invention is to provide a gas mask carrier having a metal cover afiording a hermetic seal.

A still further object of this invention is to provide a gas mask carrier having a closure equipped with a device for insuring ready removal of the closure irrespective of the ordinary inequalities of solder application at the time of assembling the carrier.

With these and other objects in view which may be incident to our improvements, the invention 46 consists in the parts and combinations to be hereinaiter set forth and claimed, with the understanding that the several necessary elements com= prising our invention, may be varied in construction, proportions and arrangement, without departing from the spirit and scope of the appended claims.

In order to make the invention more clearly understood, we have shown in the accompanying drawings means for carrying the same into practical efiect without limiting the improvements in their useful applications to the particular constructions, which for the purpose of explanation, have been made the subject of illustration.

In the drawings forming a part of this specification Figure 1 is a perspective view of the gas with an inwardly projecting head 4 near the mask carrier forming the subject matter or this application shown with a preferred form of opening device mounted thereon.

Figure 2 is a perspective view of the carrier showu-inl igure 1 having a portion of the closure broken away showing the assembly in section.

Figure 3 is a perspective view of the gas mask carrier showing another form of opening device.

Figure 4 is a side view of the carrier shown in Figure 3 having a portion of the closure broken away shown in section. I

Figure 5 is a perspective view of a gas mask carrier showing still another form of opening device mounted thereon.

Figure 6 is a side view of the carrier shown in Flgurefi having a portion of the closure broken away shown in section.

Figure 7 is an enlarged section .01 the arrangement of the covers and levers of Figures 1 and 2.

Referring more particularly by numerals to the drawings in which the same and similar elements are designated by like symbols 0! reference throughout and more especially to Figure 2', there is shown a receptacle 1 adapted for use as a gas mask carrier, having a conventional bottom closure 2 crimped .over the bottom rim. and soldered as necessary to insure a hermetic seal. Y

The receptacle 1 is ribbed as at 3 toadd to the rigidity of the structure thereof and is formed topedge. An inner cover 5 having a downwardly projecting flange 6 formed integral therewith is adapted to be fitted in the interior of the receptacle flush with the rim thereof and the bottom of me flange 6 seated on the head a.

The upper edge of the ring 9 projects above the rim of the carrier to act as a guard for the shim metal seal 7, the flange on which, is soldered to the inner face of the ring. Ring 9 is turned inwardly at its lower edge to form the flange 11.

A top cover 12 having a downwardly projecting flange i3 fitted over the top edge of the ring 9, is secured to the carrier on one side by a flexible hinge l4. It will be particularly noted that the outer cover 12 rests on the top of the ring 9, pro jecting above the rim of the carrier so that a space 15 is left between the shim metal seal 7 and the outer cover, which is adapted to allow for swelling of the inner cover and seal in the 105 event of expansion of the fluid contained in the carrier.

In the preferred form of opening device as shown in Figures 1 and 2, a bolt 16 projects through the inner cover 5 and intermediate seal no cover 7 to which it is soldered to an airtight joint, and outer cover 12 where it is adapted to retain a iug 17 positioned on the top cover opposite the flexible hinge 14, and held by a nut 18..

A plurality of toggle links 19 and 21 are pivoted on the lug through a pin 22 and the opposite ends thereof pivoted to a lever 23 through a pin 2d. The top oi the lever 23 is bent inw as at 25 and a pin 26 projecting bite sides thereof fixedly mounted therein. A plurality of hooks 27 are riveted to the Knee oi the carrier on each side oi the lever 22;, pted to receive the pin 26.

' The lower end of the lever 23 is formed with a transverse handle 29 having an aperture therein through which is threaded a wire 31 also pwed through an eyelet 32 soldered to the how i of the carrier, and the ends of the wire held-in a lead car sxaal 33. It will be apparent that any other manner of retaining the lever 23 in post tion when it is not desired to remove the closure may be employed in place of the arrangement v described.

When use of the mask contained in the carrier is required, the lever 23 is raised, pulling the wire 31 through the closed perforations in the car seal and releasing the handle for a more secure grasp. The lever 23 is then rotated about the pin 26 resting in the hooks 27 and continued movement of the handle raises the lug 17 by upward movement of toggle links 19-21. This in turn pulls inner-cover 5 upward due to bolt 16, and since seal cover 7 is of frangible material. causes the inner cover 5 to be drawn through the intermediate seal cover '7, and the three covers completely and simultaneously removed.

In Figures 3 and 4 there is depicted a modified form of opening device shown mounted on a container similar to that illustrated in Figures 1 and 2. In this form at closure, however, the ring 9 extends below the indentation iormed by the bead e on the carrier, and the inturned flange 11 is provided with an extension 34 soldered to the body of the container below the indentation.

Also the flange 6 and a portion of the cover it is cut away adjacent the opening device as shown at 35.

cutting blade 36 is mounted on a lea? spring 3? or other flexible support attached to the under side of the bottom cover 5 adjacent the cut-away portion so thdt the blade is? allowed to contact with the intermediate seal cover 7. A wire 3d connected to the support 3'? carrying the blade is passed through the intermediate cover I and the outer cover 12, the same being soldered to the intermediate cover as at 39 to insure an airtight ioint.

The lower end oithe wire is tied in an eyelet 41 having a transverse handle 42 formed integral therewith. In this construction the wire 31 is passed over the handle and through the eyelet 32, the ends, being in the lead car seal 33 in the same manner as that already described with reference to Figure 1.

simultaneously removed the same as has been previously described with regard to preferred emboent of this invention.

Still another form of closure and o dc= vice is shown in Fla urea 5 and d. In this form oi closure the inner ooverand intermediate seal. so aswell asthe ring 9, are dispensed with and the flanges 13 of the top cover 12 fitted directly over the rim or the carrier. The cover i2 is secured in position by strips 43 which be made oi a metal. These strips are bent to 5 to a hook cross section through which is passed a heed wire is secured at its inner end to the cover it and the opposite end passed out. The bent over portion of the strip at is soldered 1 to the e 1.3 of the cover and the lower edge as soldered to the body oi the carrier.

A ring as having the rim flush with the rim of the carrier is provided with an inward extension to having downwardly projected flange t?- formcd thereon soldered to the body or the corn oi; tainer, adapted to act as a guard to protect the The free end of the Wire i l extending through a notch to in the ring provided for the outlet thereof. is tied through the eyelet il in the same we manner as the wire 38 described in Figure 3. In this form of device, opening oi the carrier is eifected by tearing the seal is by grasping the handle 42 and pulling up on the wire 44, the cover 12 being carried away with the wire.

vIt will be appreciated from-the foregoing that the several opening devices illustrated lend to a positive rupture of the seal in any one 01 the types 01' closures described with the simultaneous v removal of the complete closure assembly. Also no that the provision or a metal hermetic seal in the form of a cover protected against internal or external injury eliminates the likelihood of corrosion existing in rubber or composition seals when exposed to air or other deteriorating influences over long periods.

There accomplished by this invention a carrier for gas she having a metal hermetic seal protecmd against external mechanical injury and internal pressure resulting from expansion or contraction of the iluld contained in the carrier due to temperature changes, which may be quickopened and functioning of the device insured irrespective of ordinary inequalities of solder application during assembly of the carrier.
